How can I assign an iPhone text tone to a specific contact?
Much like with ringtones, you can make sure you always know who sent a text by assigning text tones to contacts. To assign a text tone other than the default text tone to a contact follow these instructions:
1. Open your Contacts.
2. Select the name of the contact you wish to customize.
3. Touch the Edit button in the upper right corner of the screen. Scroll down and select text tone.
4. Choose the desired text tone from the list. The text tone will play.
5. Press the Save button.
6. Now when that contact sends a text you will hear the selected text tone.
